History of the Dayton Section of the American Chemical Society The beginnings of the Dayton Section date back to 1929. The first official Chair of the Section was Dr. C. A. Thomas, who served from 1931-1932. Our current membership is about 450, covering the counties of Montgomery, Greene, Miami, Clarke, Preble, and Darke. Section meetings, featuring national and local speakers, are held quarterly and include a local poster session. In addition, the last meeting of the year honors the 50-year and 60-year members. The Section has a long history of administering local philanthropy:
The Patterson High School Chemistry Awards go to winners of the Patterson High School Chemistry Competition, which consists of two stages: examination and essay. First, second, and third prizes are $1000, $750, and $500. Originally established by Charles A. Thomas and Carroll A. Hochwalt, former Dayton chemists and Monsanto researchers, the top chemistry students in the area have been recognized since 1943. In 1990, the family of the late Austin M. Patterson, also a prominent Dayton chemist, assumed sponsorship.
Last year, a new competition was offered to encourage high school students who have an interest and aptitude in chemistry to persist in their STEM education. This competition is open to any chemistry student enrolled in one of the high schools within Dayton City Schools. The Marie Daly Award is named for Marie Daly, who in 1947 became the first African American woman to earn a Ph.D. in chemistry. This competition will be continued this year.
Recipients of The Patterson College Chemistry Awards are chosen by the faculty of each of the universities within the Dayton Section from their outstanding junior chemistry majors using the general criteria of scholarship, character, extra-curricular involvement, and potential for success after college. Winners receive a certificate of recognition and a check for $400.
The Patterson-Crane Award was originally established in 1949 as the Austin M. Patterson Award to acknowledge meritorious contributions to chemical literature and documentation of chemistry. Dr. Patterson was the first recipient for his work as editor of Chemical Abstracts from 1909-1914. The biennial award was expanded in 1975 to honor another Chemical Abstracts editor (1915-1958) and 1953 award recipient, E. J. Crane. The award, which includes a monetary honorarium, is now funded by a bequest of the Patterson family, by the Helen G. Crane Fund of the Columbus Foundation, and by the Patterson-Crane Award Fund of the Dayton and Columbus Sections.
The Dayton Section also participates and supports the Dayton/Miami Valley TechFest,
and contributes funds and judges for the West District Science Fair.

History of the Society for Applied Spectroscopy
The Society for Applied Spectroscopy (SAS) is a non-profit, international, professional membership organization for scientists in all fields of spectroscopy, including physics, chemistry and other allied sciences. SAS is dedicated to those interested in all phases of spectroscopy: the science and art of light absorption, light emission, Raman scattering, and related forms of light-matter interaction for determining the composition and structure of matter.
History of our Host Venue
The history of Central State University, an 1890 Land-Grant Institution begins with our parent institution, Wilberforce University (WU), named in honor of the great abolitionist William Wilberforce. Established in 1856 at Tawawa Springs, Ohio, WU is affiliated with the African Methodist Episcopal Church and is one of the oldest Black-administered institutions of higher education in the nation. In 1887, the Ohio General Assembly enacted legislation that created a Combined Normal and Industrial Department at Wilberforce University. The objectives of this new state-sponsored department were to provide teacher training and vocational education, and to stabilize these programs by assuring a financial base similar to that of other state-supported institutions. The statue establishing the Combined Normal and Industrial Department declared that the institution was “open to all applicants of good and moral character” thereby indicating no limitations as to race, color, sex, or creed. It was clear, however, that the Department and its successors were designed to serve the educational needs of African-American students. Although this Department operated as part of Wilberforce University in most respects, a separate board of trustees was appointed to govern the state-financed operations. In 1941, the department expanded from a two- to a four-year program, and in 1947, it legally split from Wilberforce, becoming the College of Education and Industrial Arts at Wilberforce. The name was changed in 1951 to Central State College, and in 1965, the institution achieved university status. The University has grown steadily since its’ founding. In recent years, it has added new academic programs, established a new College of Science and Engineering, constructed a new academic building, four new residence halls, and began the construction of a new University Center scheduled for completion in Fall 2015. In February 2014, the 113th Congress of the United States designated Central State University an 1890 Land-Grant Institution. This designation is a distinct recognition for an Ohio institution of higher education, and Central State is one of two institutions to hold this distinction. The major impetus of the designation is to provide access to education and to promote opportunities for students with interest in Science, Technology, Engineering, Mathematics and Agriculture (STEM-A) integrated through all academic disciplines. In tandem with progressive academic achievement, the University has embodied tenets of Service…Protocol…Civility®. Its faculty, staff, and students will provide service to the institution, and various communities for the greater good; be guided by protocol and adherence
P a g e | 4
to best practices in order to gain desired results; and actively demonstrate civility with the understanding that respect for each voice is essential to a learned society. Much more has changed at Central State University throughout its history. However, one constant is the commitment to providing an excellent, affordable education to the residents of Ohio and beyond. In concert with the mission of the University, Chemistry faculty foster the professional development of students through academic excellence, and provide educational opportunities to students to be competitive in a technological society. The specific objectives of the discipline are to provide students with; 1) a thorough understanding of basic and modern concepts of chemistry and 2) the ability to analyze and apply chemical concepts to technical problems through the development of laboratory skills. Opportunities exist for undergraduate research experience, both on campus and through summer internships. Development of a strong sense of professionalism, with the motivation to pursue graduate study is encouraged. Professional programs include preparation for dental, medical, pharmacy and veterinary schools. An option in forensic science will prepare students for jobs or graduate school in forensic science. The program leads to a Bachelor of Science; in addition, a student may receive a B.S. degree in Secondary Education in middle school education in the Physical Sciences. 129 Years of Service and Excellence 1887–2016 The Dayton Section of the American Chemical Society thanks Provost and Vice President for Academic Affairs, Charles Wesley Ford, Jr., Ph.D., Chemistry Department Interim Chair, Dr. Ibrahim Katampe, as well as all the department faculty and students of Central State University for welcoming, hosting, and providing support for the 2016 ACS Poster Session.

Abstract
Insulating SiO2 films can be produced by hydrolysis of metal alkoxide
tetraethylorthosilicate (TEOS) in the presence of an acid catalyst in supercritical CO2 (sc-
CO2). SiO2 films are formed on substrates using TEOS as a source of silicon, and acetic
acid (HAc) as a catalyst. The chemical equation of the SiO2 film formation can be
expressed as Si(OCH2CH3)4 + 2H2O -- SiO2 + 4CH3CH2OH. Water required for the
hydrolysis is from in situ generation of esterification reactions involving HAc and the
alcohol produced. Without the catalyst, the hydrolysis of TEOS proceeds very slowly.
The acid catalyzed deposition reaction actually starts at room temperature but produces
decent films in sc-CO2 at moderately high temperatures. Supercritical CO2 is known to
have near zero surface tension and provides an ideal medium for fabrication of SiO2
films. Formation of SiO2 films via hydrolysis in sc-CO2 is more rapid compared to the
traditional hydrolysis reactions at room temperature. Metal alkoxide hydrolysis reactions
carried out in a closed sc-CO2 system is not affected by moisture in air compared with
traditional open-air hydrolysis systems. Using sc-CO2 as a reaction medium also
eliminates undesirable organic solvents utilized in traditional alkoxide hydrolysis
reactions. The ATR-FTIR, EDS, XRD, XPS spectroscopy, and electron diffraction (ED)
measurements were conducted to characterize the films. XRD and ED measurements
demonstrated the SiO2 films produced were amorphous. EDS, ATR-FTIR and XPS
spectra showed elemental composition of the films formed on the substrate surfaces to be
SiO2. The amount of catalyst on the film thickness is discussed.

Abstract
A series of poly(arylene ether)s was synthesized by the nucleophilic aromatic
substitution (NAS) polycondensation reactions of N,N-dialkyl-2,4-
difluorobenzenesulfonamide and N,N-dialkyl-3,5-difluorobenzenesulfonamide. The
sulfonamide-activated monomers were synthesized by reacting 2,4- and 3,5-
difluorobenzenesulfonyl chloride with a series of dialkyl amines, ranging from n-propyl
to n-octyl. The poly(arylene ether)s, prepared with bisphenol-A as the nucleophilic
reaction partner, were characterized by 1H and
13C NMR spectroscopy, TGA, DSC and
SEC. The thermal properties of the N,N-dialkyl-2,4-difluorobenzenesulfonamide
polymers were compared to those of the N,N-dialkyl-3,5-difluorobenzenesulfonamide
system. Poly(arylene ether)s prepared from the 2,4-monomers possessed consistently
higher glass transition temperatures than those from the 3,5-monomers. While the 5%
weight loss temperatures were similar for both systems, there were observable differences
in the TGA traces, indicating that the decomposition pathways may not be the same.
